Coating corona pen

The coating corona pen releases high-voltage corona through its tip, creating a discharge on the surfaces of materials such as plastics and metals to alter surface wettability. It is used to test the effectiveness of coating treatments, ensuring adhesion for printing and coating applications. It is commonly employed in quality control within the packaging and film industries.

The Taber Abraser evaluates the wear resistance of coatings.
The Taber abrasion tester simulates surface wear of materials through rotational friction, used to evaluate the wear resistance of coatings. During testing, a grinding wheel is used to rub the specimen under a fixed load, and performance is quantified by measuring mass loss or thickness changes after a specified number of cycles.
Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
Eddy current thickness gauge measures metal coatings on non-conductive substrates.
The eddy current thickness gauge utilizes the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil to induce eddy currents in the metal coating, thereby measuring thickness based on changes in coil impedance.
Coulometric Method Coating Thickness Gauge for Non-Destructive Measurement of Precious Metal Coatings
The coulometric coating thickness gauge measures the thickness by calculating the amount of electricity required to dissolve the precious metal coating through the principle of electrolytic dissolution. This method is non-destructive to the overall sample, only forming tiny electrolytic spots.
Application of Electrolytic Thickness Tester in Quality Control of Precision Electroplating Layers
The electrolytic thickness gauge measures coating thickness through the principle of electrochemical dissolution, calculating based on Faraday's law, offering high accuracy and independence from calibration.
Applicable Scenarios for Neutral Salt Spray and Copper-Accelerated Acetic Acid Salt Spray Tests
Neutral salt spray testing and copper-accelerated acetic acid salt spray testing are both accelerated methods used to evaluate the corrosion resistance of materials, simulating saline environments to predict long-term performance. The neutral salt spray test uses a neutral sodium chloride solution, which causes relatively mild corrosion and is suitable for general metals and coatings, such as automotive parts.
Selection of Coating Thickness Measurement Methods: Coulometry vs. Dissolution in Electrolytic Thickness Gauges.
This article compares two techniques in electrolytic thickness gauges: the coulometric method and the dissolution method. The coulometric method measures coating thickness through electrochemical dissolution, making it suitable for single-layer metal coatings with simple operation and high accuracy. The dissolution method, on the other hand, measures thickness via chemical dissolution, making it more appropriate for multilayer or complex coatings.
